MacBook Pro with Catalina 10.15.3 very slow after updating to Xcode 11.4.

Last night I made the update to the latest Xcode and this morning I try to open the apps from my OS X they are very slow both when opening and using them. I have repaired the user privileges but it has not served.

Thanks for the help, but I think I have solved it.

All of this happened when I updated my system with Xcode to the latest version today, but that was not the reason.

I also had to switch providers, and this seems to have network problems. I have found that if there are network problems, even simply opening a program like BBedit can be very long.
